Error message while uploading code to my Arduino Mini

Hey, so I've been working on some code recently to build a lidar. All was well till I switched computers and now, every time I try and upload my code to my Micro, I'm getting some error messages. I cannot figure it out.
Any help will be appreciated.

Thanks

Is the Micro actually attached to COM1? That would be rather unusual.
